Pancreatic carcinoma is a highly aggressive tumor that usually presents when it has already metastasized. Therapeutic options for cure remain scarce and rely on combination chemotherapy with limited sustainability. Diabetes is considered an important risk factor for the development of pancreatic cancer due to the production of proinflammatory cytokines, which result in increased cell proliferation. More than half of patients diagnosed with pancreatic cancer eventually develop diabetes due to the destruction of insulin-producing cells. The interlinkage of both diseases might identify a possible preventative strategy for reducing the incidence of pancreatic carcinoma. This study reviewed the recent literature on the association between pancreatic cancer risk and SGLT2 inhibitors, GLP-1 RA, DPP-4 inhibitors, and biguanides. There are mixed data regarding the relationship between GLP-1 RA and DPP-4 inhibitors and pancreatic cancer, with some trials suggesting that they might increase the risk. In contrast, studies have mostly revealed that SGLT2 inhibitors have an antiproliferative effect on various tumors, such as liver, pancreatic, prostate, bowel, lung, and breast carcinoma, which might be due to their mechanism of blockage of reabsorption of glucose by cells, lowering the amount of available glucose for the growth of tumor cells. Metformin, the first-line agent for diabetes, has also been shown to be associated with decreasing pancreatic cancer risk and improving prognosis in those who already have the disease. Dedicated trials are needed to further delineate the association of antidiabetic drugs with the risk of pancreatic cancer in the general population, as previous studies have mostly focused on diabetic patients.
Uterine rupture is a rare disease, which usually presents in the form of a life-threatening emergency. It occurs most commonly after a vaginal birth after cesarean (VBAC) and is characterized by complete separation of the uterine incision throughout most of its length, involving all layers of the uterus. We present the case of uterine rupture in which the patient had no acute signs of rupture; instead, she presented with symptoms of generalized peritonitis. She presented 23 days after VBAC, with complaints of slight vaginal bleeding and a palpable abdominal mass. Leukocyte and platelet counts were raised, suggesting infection, which occurred due to the spread of fluid from the uterus to the abdomen through the scar defect. A total abdominal hysterectomy was performed due to widespread adhesions and a non-viable uterus. Our case was unusual as the presentation was delayed, with no acute symptoms of either uterine rupture or peritonitis. Uterine rupture can be fatal if not recognized and managed promptly.
Chimeric antigen receptor T cell therapy is used to treat hematological malignancies which are refractory to standard therapy. It is a form of immunotherapy in which a patient’s T cells are programmed to act against tumor cells. We discuss the process of manufacturing CAR-T cells, the common side effects of therapy, and the recent emerging risk of T-cell malignancies after treatment.

Pierson syndrome is caused by mutations in the laminin β2 gene causing absent β2 laminin, which is a normal component of the basement membranes of the mature glomerulus, structures in the anterior eye and neuromuscular junctions. The mutations manifest as congenital nephrotic syndrome and microcoria which are characteristic ocular features of this disease. These mutations may also result in neurological abnormalities such as hypotonia and psychomotor retardation. We report a two-month old boy who presented to the Pediatrics Department of Dr. Ruth K. M. Pfau Civil Hospital, Karachi, Pakistan, in 2015, with the typical features of microcoria and congenital nephrotic syndrome. The hypocalcaemia, hypoproteinaemia and probable immunocompromised state consequent to nephrotic syndrome resulted in seizures, hypothyroidism and urosepsis. Despite being treated aggressively with high dose antibiotics, ionotropic support, angiotensin-converting enzyme inhibitors, thyroxine replacement and nutritional support, the infant died due to significant multiorgan disease including renal failure and septic shock.
